In the following description of the present invention, generally with reference to diagnostic imaging system and with reference to particular diagnosis imaging form as an example.It is to be understood that the features and advantages of the present invention are applicable to the diagnosing image form of many types, even and when at specific modality certain feature being discussed, identical or corresponding feature equally also is applicable to other imaging form.
With reference to Fig. 1, the block diagram of diagnostic imaging system 10 is shown.Diagnostic imaging system 10 comprises the scanner hardware 12 of being controlled to obtain the image of sweep object by system control device 14.Therefore, system control device 14 comprises scanner control module 24, and it is used for providing the scanning details to scanner hardware 12, for example scanning position, scanning duration, x transmitted intensity, RF pulse train, ultrasonic intensity etc.The processing module 28 that system control device 14 also comprises reception by the data acquisition module 22 of the scan-data of scanning generation and handles scan-datas such as being used for scanning location in future, image reconstruction.
One or more external device (ED)s 16 can be used to monitor sweep object, and provide data to system control device 14.Monitoring equipment 16 can comprise ECG probe, oximeter, blood pressure monitor and other similar device.System control device 14 is controlled contrast medium transport device processed 18 also.In certain embodiments, contrast medium transport device 18 can be the contrast agent pump that the control contrast agent is carried to the sweep object vein.In other embodiments, contrast medium transport device 18 may just notify people about when injection of contrast medium or bolus (bolus) or the indicator of administration of contrast agents or bolus when.This indication also can show in the user interface 20 of system control device 14.
Interface 20 is used for allowing operator's input scan object or patient information, selects sweep parameter, and the control contrast agent is used, and control location (scout), bolus and image scanning etc.As the description of carrying out below, in conjunction with the dynamic data from sweep object monitoring equipment 16, be used for determine coordinate image data acquisition and the peak contrast scanning/infusion protocol of enhancing time by the protocol module 26 of system control device 14 in the static scanning object information of user interface 20 input and sweep parameter.
With reference to Fig. 2, a flow chart is shown, illustrate according to one embodiment of present invention, be used for the technology that the control contrast strengthens diagnosing image scanning.This technology begins with the static data of importing new sweep object in step 30.This data can comprise the parameter such as object age, sex, weight, height etc.System can be according to these calculation of parameter Body Mass Index (BMI) values, and perhaps the operator can import the BMI value.Subsequently, in step 32, the anatomical structure (anatomy) of selecting scan type and identification to be paid close attention to.For example, the operator can to specify pending scanning at the CT work station be for the conventional helical scanning of the spine imaging of object or for the CT vasography scanning of the carotid artery imaging of object.As another example, it is diffusion-weighted imaging (DWI) scanning of carrying out for the aorta of object that the operator can specify pending scanning at the MR work station.
In case imported the type of scanning and the anatomical structure of being paid close attention to, then can carry out location scanning in order to provide locator data for next image scanning in step 34.Similarly, can carry out test injection in step 36, to guarantee correct entry needle placement and to prevent from exosmosing.Also can record the maximum pressure during the injection.
Except sweep object discussed above and scan-data, also can import the relevant parameter of contrast-medium injection in step 38.This class parameter can comprise: the type of contrast agent to be used, concentration and volume, the volume of timing to be used or tracking contrast agent, application route (oral, intravenous injection), application process (automatic or manual), entry needle type and specification, and whether have outer efflorescence.As alternative scheme, the parameter that contrast-medium injection is relevant can be imported before location scanning and test injection or in the process.
In step 40, system can begin to monitor the sweep object dynamic parameter.These parameters can comprise other statistics that heart rate, blood pressure, breathing rate or average breathing cycle, ECG signal and the external equipment by monitoring target obtain.Can monitor dynamic parameter during whole technique is handled, perhaps system may just begin to monitor dynamic parameter before agreement is calculated.
In certain embodiments, carry out regularly bolus scanning in step 42, with the rise time density curve.That is to say the perfusion of the bolus of opening entry by being subjected to region-of-interest when regularly bolus scanning is from injection.From the density and position measurement of time density curve, but labelling stabs with the projection peak contrast enhancing time time corresponding by the similar fashion applied contrast medium.For example, in the CT imaging, time-activity curve can be to be the contrast enhancing chart in time of unit with Heng Shi (Hounsfield) unit.
By user's input and after the scanning of timing bolus is obtained, in step 44, the actual peak contrast of using that contrast agent can calculate in system strengthens the time in data.By considering static and dynamic scan image parameter, injection parameters, sweep parameter and/or bolus scan-data regularly, system can predict exactly that contrast agent therein will provide the time after the injection of maximum-contrast enhancing.Known the persistent period of scanning, system can provide time-delay before the scanning beginning, make scanning consistent with the cycle that maximum-contrast strengthens.
In step 46, scanning and infusion protocol that system will follow operator specified.Like this, the operator knows that contrast-medium injection begins and the selection of time of Image Acquisition between beginning.Can be the operator in step 48 provides the affirmation agreement or changes parameter to set up the chance of different agreement.In case confirmed agreement, the operator can be in step 50 administration of contrast agents (manually or automatically), and after the time-delay of scan protocols defined, begins scanning in step 52.
As alternative scheme, embodiments of the invention can make the some steps automatization in these steps.For example, can replace regularly bolus scanning by administration of contrast agents group together with contrast agent and pour into real-time driver sweep according to bolus and begin.Like this, affirmation step and a lot of calculating can be carried out immediately.In addition, the dynamic data that provides of sweep object monitoring equipment can be used to regulate automatically the selection of time of scanning.For example, if patient's heart rate or blood pressure increase, then can accelerate the perfusion of contrast agent.System can consider this class variable in real time, and the beginning of accelerated scan.
In further embodiments, system control device also can be according to the expection automatic adaptive sweep parameter of view data and contrast-medium injection parameter, as to adaptive the replenishing or substituting based on the dynamic scan object data.In administration of contrast agents and when beginning to scan, obtain view data from ROI.According to the view data of obtaining in real time, system can determine the current enhancing value of the contrast agent among the ROI, and real-time update or adaptive flow or parameter such as pressure, x ray tube current or voltage, x roentgendosis, scanning resolution, view data weighting, Image Acquisition track such as injection process.Correspondingly, if view data shows contrast and strengthens than estimate more Zao or reached or will reach its peak value enhancing value lateer, then system can regulate the scanning contrast level parameter immediately, makes image data acquisition or its specific part still consistent with the time that maximum-contrast strengthens.For example, in CT scan, system control device can calculate real-time adjustable pipe electric current and/or voltage based on the enhancing carried out according to the view data of obtaining, thus during peak contrast strengthens with the maximal dose scan patients.
